Pale pink octopus in prehistoric blue ocean scene

A pale pink octopus with a large, bulbous mantle and fin-like protrusions on its arms is swimming through clear, blue ocean water. Its eye is visible, a small, dark pupil within a lighter iris. The octopus is positioned in the center-left of the frame, angled slightly away from the viewer and towards the upper right. In the background, a large, gray marine reptile with a long snout and sharp teeth swims towards the right side of the frame. Sunlight filters down from the surface, creating bright rays that illuminate the water. The seabed is visible in the lower portion of the image, with rocks, coral, and a coiled ammonite fossil. A school of small fish is also present in the mid-ground. The illustration has a realistic, paleoart style, depicting a prehistoric marine environment with a dramatic and slightly ominous atmosphere.
